DH11 Temperature and Humidity Sensor With Arduino




I have a keen interest in science and Maths and i wanna share my projects with people who are als...

This is a Tutorial On how to use the DH11 Temperature and Humidity Sensor with Arduino.

Teacher Notes

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: Watch This Video ( This Is a Full Tutorial )

This video Shows the full Procedure on how to use this Sensor.

Step 2: Install the DH11 Library.

1) Click here To download the DH11 Library for Arduino.

2) Extract the Zip File.

3) Paste the Extracted Folder to C: \Program Files \ arduino \ Libraries.

4) Open the Arduino IDE and Click "OPEN".You will find that a new option has been added (dht11_read).

5) Open this Sketch and Upload this to your Arduino.

6) Thats it, You are good to go!!!!.

Step 3: Points to Remember

1) According to the sketch, Connect the Second Pin of the Sensor to the DIGITAL PIN 4 of the Arduino.Otherwise it will show an error.

2) it is not necessary to connect a 10K Ohm Resistor in between the VCC and Signal (1st and 2nd) Pin of the Sensor.

    Hi, Can use this librery for sending data by ethernet? Exist other librery, where the wat for getting data needs a delay... and your expample not use delay... I will try..

    Finally.. this library.. can works with DHT22?? or justo work with DHT11??
